Dont forget X & Y scale needed. 

 

There was a post about doing volumes automatically I think over at Forums/autodesk may be useful save some brain cells thinking about code.

 

There is some manual ways copy  all xsects block and rescale so 1:1 at true size ie metres etc, there is a break pline at point again I think it was forums/autodesk.

 

Have to do something now will try later to find very simple 2 pick.

I think this is posted over at Forums/autodesk as well and a solution suggested was to use break pline with object that does what is required. It is a seperate post, pretty sure posted post link.
